Prematurity and low birth weight contributed an estimated 36% to infant mortality in 2013 and are associated with adverse consequences, including increased risk of infant mortality and chronic health conditions throughout the infant's life. In the United States, rates of prematurity and birth weight are higher than in most developed nations, with black infants twice as likely than white infants to be born at low birth weight and 1.5 times as likely to be premature compared with white infants.
